The Lowdown

G’day, Rusty here. Look, the next couple of weeks are a bit of a quiet stretch for your local beach, Kennebunk Beach. The surf is going to be pretty small and marginal most of the time, with onshore winds and short-period wind swell that just won’t clean up. There are a few isolated moments where things look surfable, but nothing to get too excited about. Let’s break it down.

We kick off with a bit of a dud right now. Monday the 31st of August stays tiny with a 1ft south-east wind swell and an 8-second period. Morning is cross-off and clean, but with only 11 units of combined energy, it’s barely a ripple. The afternoon gets a bit sloppy with cross-onshore wind. Tuesday and Wednesday stay small and weak, though Wednesday morning sees the swell nudge up to 2ft with a longer 11-second period, and it stays clean with cross-off wind. Energy climbs to 92, but it’s still small.

Thursday the 3rd of September sees a spike in swell—7ft from the south-south-east—but it’s short-period junk at 6 seconds, with a moderate cross-onshore blow making it choppy and poor. Too big for the wave quality on offer. Energy hits 333, but it’s not worth paddling out for.

Now, here’s the best we’ve got. Friday the 4th of September shows some promise. The morning has 4ft from the east-south-east at 7 seconds, morning is clean with cross-off wind (143 energy). But the real standout is the afternoon: glassy conditions, 3ft swell from the east-south-east at 8 seconds, and 123 energy. That’s the cleanest window in the whole run. It’s a small, ordinary wave, but with zero wind, it’s your best chance for a fun session.

Saturday the 5th and Sunday the 6th go back to being messy and strong—7ft north-east wind swell (energy up to 604) but with strong onshore winds and short periods. Not for paddling. Monday the 7th offers a clean 4ft east swell with a long 11-second period and offshores, but the quality is still just ordinary.

After that, from the 8th of September right through to the 15th, it’s a long, quiet run. Tiny swell—1ft to 2ft—with low energy (under 65 most days) and variable onshore or cross-shore winds. Surfable, sure, but you’ll be lucky to get a wave worth paddling for.

So look, the standout is the glassy Friday 4th of September afternoon session. Get on it. Everything else is a write-off or very marginal. Water temps are about what you’d expect for this time of year, no major anomalies. Keep an eye on the charts, but for now, it’s a waiting game.

Stay salty,
Rusty

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
